Re: Diagnostic code P1447

P1447, the definition for Ford vehicles is "EVAP System Purge Flow
Monitor."
No difference really. The code points to a problem with the vacuum control

valve that controls the opening and closing of your EVAP charcoal canister
that captures gas vapors from the gas tank. As far as I can tell, the
canister rarely goes bad, so there might be a problem with the vacuum hoses
to the canister, the circuitry to the valve/sensor, or the valve/sensor
itself. Examine the hoses for blockage or breaks first, before you check the
circuit, or the vacuum control valve.
